After the First world war, France had the largest tank Park in the world. And the main part of it were the fighting vehicles Renault FT17— without a doubt the best tanks of the last war, which allowed them not to hurry with the creation and adoption of new models of armored vehicles. However, in 1926, he developed the first post-war concept of development of armored forces. The armament of the infantry was supposed to have three types of tanks: light, medium (or “combat”—weighing up to 20 tonnes) and heavy.

Unfortunately, in Russia, still little known very interesting and popular abroad, the subclass of radio-controlled gliders, the name of which in translation from most foreign languages sound like “throwing the glider”.
In the design of devices and equipment before the radio often question about their design: sometimes they place boards and panels of their devices in boxes that slides, fishing gear and other containers. Ham D. Plewinski offers as buildings to use more modern products — cases videokasset: they have a low cost; plastic from which they are made, can be easily processed.
To the two parts worked as a whole — they should be connected to. Where possible, use bonding, soldering or welding, but all these options are permanent fixtures. And here is the bolt to nut connection is universal: he is subject to any material, and if necessary disconnect them tight elements of the design — this fixture is easy to Unscrew. However, such a connection provides the necessary resistance only when the bonded parts are inactive; and in the event of impact, for example, vibration can fail because of such insidious phenomena as samothracian.
It would seem that this device has already acquired a classical form; in any case, each representation there is a tool with movable and stationary jaws, and a screw feed. However, innovators are creating new kinds: specific and universal. That’s the job of the innovator K. Malkova (Leningrad plant conveying systems named after S. M. Kirov). His grip is possible, first, to simultaneously process multiple parts. Secondly, they are easy to attach versatile-modular fixtures. Finally, the vise can be used for installation on the drilling machine to facilitate the clamping of large parts.
If you still have segments of a durable fabric, you can sew a voluminous shopping bag—for example, work in the garden. Two identical rectangle of fabric on three sides are connected by one long, narrow flap—rectangular shapes. Get the product, having the form of a box without a lid.
A variety of roller chain, like a Bicycle or a motorcycle, are used on many machines, including most agricultural units. With their Assembly during the repair of machines of great assistance can provide a simple tool offered by pioneer A. Yurchenko (see figure).
